138434-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138434-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,3 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138434-64:
(8*1)+(7*3)+(6*8)+(5*4)+(4*3)+(3*4)+(2*6)+(1*4)=137
137 % 10 = 7
So 138434-64-7 is a valid CAS Registry Number.
